About the Airtac SE125 Standard Cylinder SE125X160
The AirTAC SE125X160 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a formidable 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel entirely eliminates external tie rods, yielding a highly compact, corrosion-resistant body that mounts flush against machine frames while retaining the standardized ISO 15552 interface for seamless retrofitting.
This 125 mm bore unit travels a 160 mm stroke and relies on a 40 mm field-adjustable air cushion at both ends to decelerate massive payloads smoothly, preventing harsh end-stop collisions. This specific SKU is built without a position sensor magnet, operating reliably at speeds of 30-500 mm/s without relying on electronic feedback.

Where the Airtac SE125 Standard Cylinder SE125X160 Is Used
Injection Mold Clamping
Provides the immense 6136 N push force required to secure heavy injection mold halves during high-pressure plastic injection cycles.
Hydraulic Press Ejection
Utilizes its 125 mm bore and 160 mm stroke to eject dense metal or composite parts from hydraulic press beds reliably.
Pallet Lift Gates
Drives heavy-duty automated pallet lift gates where the 5734 N pull force safely retracts loaded platforms without drift.
Is the Airtac SE125 Standard Cylinder SE125X160 the Right Cylinder?
Selecting this 125 mm bore model is appropriate when an application demands up to 6136 N of push force at 0.5 MPa. If your load requirements are lighter, stepping down to the 100 mm bore yields a 3927 N push, whereas this SE125X160 provides the maximum standard thrust in the series at 1252 kgf when pressurized to 1.0 MPa. Because this is a plain double-acting cylinder, it cannot hold a load in place if air pressure is lost or the valve is centered; a BSE rod lock variant is required for fail-safe holding.
For dimensional replacements, verify the 160 mm stroke, PT1/2 port, and required mounting accessory. Since the stroke is under 300 mm, the rigid 32 mm rod and M27x2 thread handle standard side loads adequately, though heavy lateral forces still warrant an external guide.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE125 Standard Cylinder SE125X160 FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N, with an absolute maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, its standardized ISO 15552 dimensions and PT1/2 port make it a drop-in replacement for other ISO 15552 profile cylinders. However, it is a standard double-acting cylinder, so the adjustable air cushions only decelerate the piston near stroke end; they do not hold the load if air is lost. For position holding, use a BSE rod lock.
